Ranking System with S&P 500 Universe

Could someone explain to me the theory behind why every bucket in a ranking system whose universe is the S&P500 would have a better 10 year performance than the index itself.

I would think at least one of the buckets would underperform.


Dividends I think. The SP500 bucket isn’t going to count them, whereas all the other buckets do?

I suppose that could be it. Wish there was a benchmark that included dividends

The S&P 500 index is market-cap weighted. The stocks are equal-weighted.

It’s the equal weight thing. The best benchmark is an equal weight index which has just been made available! See this thread .
